'1'0 all whom it may concern Be it known that I, JOHN A. Bncn'rnn, a citizen of the United, States, residing at Tarentui'n, in the county of Allegheny and State of Pennsylvania. have invented cerfor the filling of pots of melting furnaces employed in the manufacture of glass and may he used in supplying cullet, batch and the like material to the pots. One of the chlef objects of the invention is the pro vision of an improved pot filling device which is of simple construction-to afford ease and effectiveness in operation. Another object of the invention is the provision of an inexpensive device which is so constructed that a nuniberof pots may be filled in an effective and simple manner Without transferring the position of the device and with a minimum of manual labor or effort. Still another object of the invention is the provision of a device which will ha\ e the advantages recited and at the same time be readily and conveniently transferable to andfroin the various furnaces and )OtS and also meet the various needs of practice. "ihese, together With such other objects as may hereinafter appear I attain by means of a construction illustrated in preferred form in the accompanying drawings of Which- Figure 1 is-a side elevation of a glass" melting .furriacepartly broken away to disclose one of its pots-showing the pot filler in position to receive a charge of batch from a hopper. Fig. 2 is a section through thefurnace showing the arrangement and location of the pots with-the filler shown in relation thereto. Fig. 3 is a side elevation of my improved pot filler drawn on alarger scale. Fig. t is a plan view of Fig. 3, and Figs. 5 and 6 are respectivelya partial section and end elevation of a detail of the invention. 3

Referring to Figure 1, I have illustrated the usual melting furnace 7 provided with a plurality of melting pots 8 arranged. in two rows to Which access is had through the sides of the furnace in the usual manner. The potfilleris "shown in position to receive a charge of batch from the hopper 23 adjacent the furnace.

Referring nor: particularly to Figs. 3 and ---i.. it will be seen that the pot filler 9' comprises a truck 10 mounted on wheels 11' and provided with a pedestal or standard 12.in

which is pivotally mounted a swinging arm 13. At th end of the arm is pivoted aclev'is like support 14 which carries a rod 15 provided with a cross handle 15 and a ladle 16. The rod is loosely mounted in the support 14 so that it can be readily turned to invert the ladle 16, but is held against cndwise movement with respect to the support by means of the collars 17 and 18 which bear on either side of the sleeve 19 which is trunn'ioned iii the support (see The angle of the rod 15 may be (aried toyertically adjust the ladle. to meet the needs of practice by means of the rollers 2-9 mounted in the block 20 slidably carried in the guideways 20 of the supporting member and by means of the eccentric 21" which is also mounted in the supporting inemherand is adapted on rotation to raise or lower the block 20?. loosely mounted and bear against the rod 15 so that the turning of the eccentric in the support will raise or depress the rollers and rod as the case may be. The position of theecccntric is fixed by means of a pin 22 which is thrust through any of the openings-22in the eccentric and a hole in the supporting, member. thereby looking it against rotation with'respect to the said supporting member. The members 20 are preferably rollers so that the rod 15 may be readily turned, in its bearing in the supporting member when it is desired to invert and 'emptythe ladle. Roller bearings 14 and 13 areprovided for the supporting member lal and the arm 13 respectively so the parts may be readily manipulated. It will be apparent that by this construction the. arm maybe shifted to any desired lateral position, the rod 15 may be shifted laterally and the angle thereof varied to suit all conditions of service, while at the same time the rod can be freely turned to invert and empty its ladle.- Several positions of the filler have been illustrated in Fig. 2, from an inspection of which it will be readily apparent that the device caphe shifted The rollers are lowing with vgreat ease-to fill several-bots without versal movement on the free end of saida'rm and f ree to rotate'about its own axis, a cha'rgmg receptacle at one end of the bar and 'a handle at theother and stop means; for vpreventing the end of the bar carrying the receptacle from swinging downwardly from a substantially horizontal position.

'2QA ladling device comprising in combinatio'nfa support, an arm pivoted to said' support for rotation about a substantially verticalaxis, a bracket mounted in'the'arm for rotation about a substantially, vertical axis, a sleeve mounted in the bracket for rotative movement about a substantially-horizontal a'z'tis, a rod rotatably mounted in the sleeve, a bearing blockslidably mounted in thejbracketand arranged to-support the rod, Ineansforraising and lowering said block, and a'ladle carried on said r0d.'

-'3. A'1adling device comprising in combin'ationa'support, an arm pivoted to said support for rotation about a substantially vertical axis, a bracket mounted in the armfor rotation about a substantially vertical axis, a sleeve mounted in the bracket for ret'ative movement about a substantially horizontal axis, a rod rotatably mounted in the sleeve, a support slidably mounted in the bracket for vertical movement, a roller mounted in said support and arranged to lVitnesses:

support the rod, cam means for raising and lowering the roller support, and a ladle carried on the said rod. i'

4:. A ladling device comprising in com- I bination, a truck, an arm mounted thereon for rotation about a vertical axis, a clevis swiveled in the arm for rotation about a vertical axis, a sleeve trunnioned on a horizontal'axis in the clevis, a rod rotatably carried in the sleeve, substantially vertical guideways on the clevis, a block slidable in said guideways, a roller mounted in said block arranged to hold the rod at a predetermined angle of inclination, a cam mounted in the clevis for raising and lowering the block, and a ladle carried on the arm.

'5. A ladling device comprising a support,

'a horizontally swinging arm carried themby, a' bar mounted intermediate its ends forlateral swinging movement and for vertical swinging adjustment on the free end of said arm, the bar being'free to rotate about its own axis, a charging receptacle at one end of the bar and a handle at the other, and adjustable means for limiting the downward swinging movement of the end of said bar carrying the receptacle.

6. A 'ladling device comprising a support,

a horizontally'swinging arm' carried thereby, a bar mounted intermediate its ends for universal movement on. thefree end of said arm and free to rotate about its own axls,

and a charging receptacle at one end of the bar'and a handle at the other end.

-. In witness whereof I have hereunto signed my name in the presence of the two subscribed witnesses.
